首先要安装swiper 依赖

引入import Swiper from 'swiper'

<div class="swiper-banner">
	            <div class="swiper-wrapper">
	                <div class="swiper-slide" v-for="(str,index) in advertising">

	                	<img src="../../../dist/static/images/ad@2x.png" :data-src="str.imgUrl" class="swiper-lazy">
	                </div>
	            </div>
	            <div class="swiper-pagination">
	            	<span v-for="(str,index) in advertising"></span>
	            </div>
	       </div>

1、
//懒加载--真正要显示的图片放在:data-src="str.imgUrl"，loading时放在src="../../../dist/static/images/ad@2x.png"  class定义成swiper-lazy
2、

现在开始mounted时初始化一下

var that = this
that.mySwiper = new Swiper(".swiper-banner",{
        autoplay: 4000,
        loop: that.paginationShow,
        autoplayDisableOnInteraction: false,
        preventLinksPropagation: true,
        lazyLoading : true,//懒加载开启
        pagination: ".swiper-pagination",
        observer:true,//修改swiper自己或子元素时，自动初始化swiper
        observeParents:true,//修改swiper的父元素时，自动初始化swiper
        onSlideChangeEnd: function(swiper){ 
		swiper.update() 
	},

}

3、

然后在你异步请求数据完成后

that.$nextTick(function() {							
	that.mySwiper.startAutoplay()//重新开始轮播
	that.mySwiper.reLoop()//重新计算slides个数
})
